Abstract

A patch plug is provided that has a coating continuous over both the patch and plug portions, providing a strong and continuous seal to prevent seal failure and water and air introduction. The patch and plug portions may be formed separately, each with a coating element, and fused together in a press which bonds the coatings of the patch and plug portions together to form a single, continuous coating. Means known in the art, for example rubber cement, can also be employed to further ensure a firm seal between the patch plug and the tire. Methods of manufacturing and using the patch plug are also taught herein.
